使用自定义单元格的编辑模式 [英] Edit mode with Custom Cells
问题描述
我已经用 IB 构建了一个自定义单元格,并将其显示在一个 tableView
上,它不会覆盖整个窗口.我设置了一个 toolbar
并给了它一个按钮,它可以切换 isEditing
属性和按钮标题.我还在 didSelectRowAtIndexPath
中制作了 if(!self.editing)
.
I've build a custom cell with IB, and display it on a tableView
, that doesn't cover the whole window.
I set up a toolbar
and gave it a button, which toggles the isEditing
attribute and the buttons title. I also made the if(!self.editing)
in the didSelectRowAtIndexPath
.
我得到反馈,当点击按钮时,我处于编辑模式,但我的自定义单元格没有在左侧显示删除符号.如果我滑动一个单元格,右侧 上的删除按钮会出现,但是如果我按下那个按钮,应用程序就会崩溃,但我稍后会解决这个问题,只是想我会这样说,在案例导致你犯了我犯的错误..
I get the feedback, that when the button is hit, I am in editing mode, but my custom cells don't show the delete-sign on the left. If I swipe a cell, the Delete button on the right appears, but the App crashes, if I push that button, but I'll address that later on, just thought I'd say this, in case that leads you to the mistake I made..
我读过,如果我不将我的自定义单元格分配给 cellforRowAtIndexPath<中的
cell.contentview
,它可能会发生它不显示左手删除符号的情况/代码>.我试过了,但出现错误.
I've read, that it may happens that it doesn't display the lefthanded delete sign, if I don't assign my custom cell to the cell.contentview
in cellforRowAtIndexPath
. I tried, and got an error.
cellForRowAtIndexPath
中的代码,我在其中分配了自定义单元格:
The code in cellForRowAtIndexPath
, where I assign the custom cell:
static NSString *CellIdentifier = @"CustomCell";
CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
for (id currentObject in topLevelObjects){
if ([currentObject isKindOfClass:[UITableViewCell class]]){
cell = (CustomCell *) currentObject;
break;
}
}
}
// some more setup and stuff
return cell;
推荐答案
由于我的 ViewController 是 UIViewController 的子类,而不是 UITableViewController,所以我需要像这样切换编辑按钮:
As my ViewController is a subclass of UIViewController, not UITableViewController, I would have needed to make the Edit button toggle like this:
- (IBAction)editButtonPressed:(id)sender {
if (self.myTableView.isEditing) {
self.editButton.title = @"Edit";
self.myTableView.editing = NO;
}
else{
self.editButton.title = @"Done";
self.myTableView.editing = YES;
}
}
代替
- (IBAction)editButtonPressed:(id)sender {
if (self.myTableView.isEditing) {
self.editButton.title = @"Edit";
self.myTableView.editing = NO;
}
else{
self.editButton.title = @"Done";
self.myTableView.editing= YES;
}
}
希望也能帮到别人..
